The Gamut Corrector offers a "legalising" function. It processes the incoming video to
ensure that it always remains within the valid RGB colour gamut. This ensures when the
signal is then coded to PAL or NTSC it will remain legal.

Functions
Display illegal This colours the out of range pixels bright pink so that it is immediately clear
what areas of the screen are illegal.

Correct illegal
When enabled, a processing engine looks at each pixel and decides if it is out of gamut.
If it is, a calculation is made of how much correction should be applied to bring the colour
back into the RGB colour space. This means that when the signal is coded to PAL or
NTSC it will always remain legal.

Split Screen
Shows a horizontal split of the picture, with legal picture in one half and illegal
(original source) in other.

Y/C Limit
Restricting the luma (Y) to digital values between 16 and 235 and Chroma (C) to
-112 to +112, clipping of below black and above white spikes.

Blanking
Applies blanking that equals the 14:9 (or 4:3) area of a 16:9 picture. This enables a quick
check to be made of where the picture edges might be once put through an ARC.
